The invention discloses an elevating gooseneck type semitrailer belonging to the technical field of transport vehicles. The elevating gooseneck type semitrailer comprises a traction exchange platform, a carrying bench and an elevating mechanism. Two sides of the front end of the carrying bench are both hinged with a delivery bench; when the delivery benches are totally put down, a panel, the upper surface of the carrying bench and the ground form a continuous surface; each delivery bench is provided with a jacking assisting mechanism helping lifting the delivery bench up; the elevating mechanism is provided with a top rod, a lifting oil cylinder and a telescopic oil cylinder; the leg part of the top rod, a cylinder sleeve of the lifting oil cylinder and a cylinder sleeve of the telescopic oil cylinder are orderly hinged to the front end of the carrying bench; a piston rod of the telescopic oil cylinder is hinged with the tail part of the traction exchange platform; a platform hinge seat is arranged in a place under the traction exchange platform and close to the tail part; the head part of the top rod is hinged with the platform hinge seat; the neck part of the top rod is provided with a top rod hinge seat; and the top rod hinge seat is hinged with a piston rod of the lifting oil cylinder. By the use of the elevating gooseneck type semitrailer, goods can be easily carried; and the traction exchange platform can be prevented from being directly rolled by an engineering vehicle, so deformation of the traction exchange platform can be avoided.
